The 1N5386B is a do-15 (dual-in-line package) zener diode device that is RoHS (Restriction of Hazardous Substances) compliant and manufactured by the LGE (LG Electronics) company. It's designed for use as a voltage-limiting device in various types of DC circuit. The device is capable of sustaining a reverse voltage of up to 5.6V in forward operating mode with a surge current of up to 200mA. The zener diodes are also good electrical noise suppressors and have a low forward voltage drop in the range of 1.39 V, with a high reverse breakdown voltage of 5.6V. The 1N5386B is designed for use in many types of applications, such as power supplies, motor controls, audio amplifiers, and consumer electronics.
